The temperature was still high at the surface and varied 

 only 4° in the upper 100 meters; the salinity and hydrogen-ion 

 concentration were very high and varied scarcely at all. The 

 vertical distribution was more even, with 22 species at the 

 surface, 29 at 50 meters, and 33 at 100 meters. Ten of these 

 species were found in all three tows, and 26 (52 per cent) were 



confined to a single tow. This is the only Atlantic record for 

 Ilaloplilus plumosus and the one locality where Lucicutia 

 longicornis was present in sufficient numbers to be called 

 common. Corycaeus, Farranula, Oithona, and Oncaea were 

 each well represented in the surface tow.

The surface tow was the only one taken at this station, with 

 temperature 26°, salinity 36.5 o/oo, and hydrogen-ion concen- 

 tration 8.37. This station still shows a high temperature and 

 high salinity. Although but 12 species are recorded, it must 



be remembered that this was a surface tow, for which 12 is a 

 very fair record. If the two other tows had been taken there 

 is no doubt that the total number of species recorded for this 

 station would have been much larger.
